Hydrogen Sulfide Process Analyzer

PT605-H2S Process Analyzer

Model PT605 H2S Process Analyzer has been designed for the detection of Hydrogen Sulfide in process streams and in Natural Gas Pipeline.

The system is cost effective yet highly accurate and reliable. An industry standard 4-20mA output and three programmable alarm relay contacts are provided. These relay contacts can be used to control shut in valves. A large LCD display with back light and push button switches on the front panel are provided for easy user interface calibration.

Also available on this H2S analyzer are real time clock and non-volatile memory for historical data logging. The unit is MODBUS RTU serial communication compatible with PLC’s, SCADA, and DCS systems. PT605 Analyzer provides complete status like current gas concentration, last successful calibration date & time and current alarm status via MODBUS link. The alarm levels can also be accessed and programmed via MODBUS.
